Review on the effect of electric field on interfacial tension and dynamics of liquid droplets
摘要
Abstract
The effect of electric field on the interfacial tension of liquid droplets is of crucial importance to the movement,deformation,splitting and merging of micro fluids actuated by electric fields,which is extensively applied in micro drop control,electronic display,crude dehydration,etc., and its applications have many potential prospects. In this paper,the effects of electric field on the interfacial tension at gas-liquid,gas-solid and liquid-liquid interface are reviewed comprehensively. The mechanism of micro droplet dynamics induced by interfacial tensions in electric fields is discussed. The related experimental studies and simulation results are summarized. The trend of gas-liquid interfacial tension in the electric field is still controversial due to the difference in the experiments and simulation. The diversiform effects of DC and AC electric fields on the spreading of the droplet and the oscillating characteristic in the process of electrowetting are discussed. Similarly,the remarkable effects of DC,AC and pulse electric field on the movement of a droplet in the process of electric emulsification are analyzed. In addition,based on research progress and existing problems,the possible prospects of electric field on interfacial tension and dynamics of liquid droplets are suggested.关键词
